Identifying word-senses based on linguistic variations

ABSTRACT

One or more words are received. A set of frequency of occurrence values of the received word(s) within a set of domain tables is determined. A domain table in the set of domain tables is associated to the received word(s), based on the set of frequency of occurrence values meeting a threshold value. A word-sense of the received word(s) is determined based on a corresponding word-sense in the associated domain table and/or corresponding domain dictionary.

FIELD OF INVENTION

The present invention relates generally to the field of computersystems, and more particularly to semantic analysis.

BACKGROUND

Use and meaning of a particular word or a phrase vary by severalfactors. Currently, several semantic analysis techniques use syntacticfeatures and consider the semantic context of a given word to identifyits word-sense using various statistical and supervised/semi-supervisedmachine learning techniques. However, none of these techniques considerdomain-specific factors such as temporal, regional, cultural, andcolloquial language variations; this could result in obtaining the wrongword-sense of a particular word or a phrase.

SUMMARY

It may be desirable to implement a method, system, and computer programproduct which considers various aspects of use of a particular word inorder to correctly semantically analyze a received word and determinethe correct word-sense.

An embodiment of the present disclosure provides a method for analyzinga word with respect to temporal, cultural, region-specific, linguistic,and other variances in order to obtain an accurate word-sense of areceived word. The method receives a word for evaluation and determinesthe frequency of occurrence and/or the frequency of co-occurrence of thereceived word within one or more domain tables. A domain table is anarray of statistical information about words and correspondingword-senses generated based on word frequency in a corpus, wordco-occurrence in a corpus, and/or domain-specific dictionaries. Themethod associates domain table(s) to the received word based onfrequency of occurrence and/or frequency of co-occurrence of thereceived word within the domain tables and determines a word-sense forthe received word based on a corresponding word-sense in the associateddomain table(s) and/or a corresponding domain dictionary.

According to a further embodiment, a system for analyzing a word withrespect to temporal, cultural, region-specific, linguistic, and othervariances in order to obtain an accurate word-sense of a received wordis provided. The system receives a word for evaluation and determinesthe frequency of occurrence and/or the frequency of co-occurrence of thereceived word within one or more domain tables. The system associatesdomain table(s) to the received word based on frequency of occurrenceand/or frequency of co-occurrence of the received word within the domaintables and determines a word-sense for the received word based on acorresponding word-sense in the associated domain table(s) and/or acorresponding domain dictionary.

According to another embodiment, a computer program product foranalyzing a word with respect to temporal, cultural, region-specific,linguistic, and other variances in order to obtain an accurateword-sense of a received word is provided. The computer program productreceives a word for evaluation and determines the frequency ofoccurrence and/or the frequency of co-occurrence of the received wordwithin one or more domain tables. The computer program productassociates domain table(s) to the received word based on frequency ofoccurrence and/or frequency of co-occurrence of the received word withinthe domain tables and determines a word-sense for the received wordbased on a corresponding word-sense in the associated domain table(s)and/or a corresponding domain dictionary.

A program, such asa Domain-based Semantic Analysis Program 108A and 108B may run on theclient computer 102 or on the server 112.

Referring now to FIG. 1B, the components of the Domain-based SemanticAnalysis Program 108A and 108B, are illustrated. Domain-based SemanticAnalysis Program 108A and 108B may include a receiving module 118A,determination module 118B, association module 118C, and analyzing module118D. Receiving module 118A may receive one or more digital textstreams, such as one or more words. Determination module 118B maydetermine the frequency of occurrence of the received word(s) within aset of one or more domain tables. Association module 118C may associateone or more domain tables (from the set of one or more domain tables)with the received word(s). Analyzing module 118D may semanticallyanalyze the received word(s) based the associated domain tables andcorresponding domain specific word-sense dictionaries.

FIG. 2 is a schematic block diagram depicting a graphical representationof content of a domain table and operation of association module 118Cwith respect to a threshold value according to an embodiment of thepresent invention. In this embodiment, content of a “temporal frequencyof occurrence” domain table for the word mafficking and operation ofassociation module 118C with respect to a threshold value are depicted.Environment 200 is a graphical representation of the content of theabove-mentioned domain table and threshold.

A domain table comprises one or more arrays of aggregated statisticalinformation about words, within a particular domain, and one or more ofcorresponding word-senses and temporal properties. Non-limiting examplesof the information about words may be frequency of usage, frequency ofoccurrence, frequency of co-occurrence with other words, year of usage,or usage within a specific profession or domain, or context of usage.Profession, for the purposes of the present disclosure is a vocation orbusiness requiring knowledge of science or traditional businessdealings. Non-limiting examples of a profession is medical, legal,paleontological, accounting, or engineering.

Non-limiting examples of a domain table comprise a table of frequency ofusage of words and their corresponding word-senses within a professionsuch as the medical profession (e.g. Profession Frequency of OccurrenceDomain Table such as Medical/Legal/paleontology/ . . . Frequency ofOccurrence Domain Table); a table of a frequency of usage of multiplewords and their corresponding word-senses when those words haveco-occurred within the same sentence or a corpus within the context of aprofession such as the legal profession (e.g. Profession Frequency ofCo-Occurrence Domain Table such as Legal/Medical/Paleontology/ . . .Frequency of Co-Occurrence Domain Table); or a table of a frequency ofusage of words and their corresponding word-senses during a specifictime period (e.g. Temporal Frequency of Occurrence Domain Table).

A domain table may be based on any language variation, therefore, domaintable(s) are not limited to profession-specific word-senses and maypertain to, among other things, colloquial, cultural, or regionallanguage variations and word-senses. For example, a colloquial domaintable may be aggregated statistical data regarding words specific tocolloquial use and their corresponding word-sense (e.g. “kicks” and itscorresponding word-sense “shoes”); a cultural or regional languagedomain table may be a table of data on different usage and word-sensesfor the same word or meaning (e.g. the phrase “fixing” has a word-senseof “about to” or “that the action described is in the very near future”in some southern states in particular Texas, however in some northernstates is has a word-sense of “repair” or “fasten securely in aparticular place or position”).

It should be appreciated that arrangement of array(s) of aggregatedstatistical information may comprise statistical information of bothtemporal properties and word-senses. For example, a domain table mayinclude frequency of occurrence of medical words and their correspondingword-senses during the 18^(th) century. In one example, the domaintable(s) may be generated by comparing usage of terms, theircorresponding word-senses and frequencies in various literature. Forexample, a domain table may be generated based on a term frequency chartgenerated by an n-gram viewer. An n-gram viewer is a phrase-usagegraphing tool which charts the count of selected n-gram as found inmillion books digitized by different companies. An n-gram is a sequenceof letters of any length, which could be a word, a misspelling, or aphrase.

In this embodiment, content of a “temporal frequency of usage ofmafficking” domain table is illustrated utilizing a graph whichcomprises X and Y axes. This domain table comprises a set of aggregatedstatistical information about frequency of usage of the word maffickingand the corresponding year of usage. In this embodiment, the X-axisrepresents chronology (e.g. increments of time, and in this caseincrements of 20 years), and the Y-axis represents the frequency of use.The Y-axis illustrates the percentage of usage of the word maffickingwithin a variety of corpuses in a particular 20-year increment of timeby performing statistical analysis on unigrams generated from GoogleBooks n-gram Viewer. Any given coordinate on the graph represents theusage of the word mafficking and the year of said usage. For example,using this domain table, one can determine that in 1895, the wordmafficking was used 0%, in 1935 the usage was nearly 0.0000016705%, orin 1945=0.0000007370%. As explained below in FIGS. 3 and 4, these valuesare used by determination module 118B in order to calculate thefrequency of usage (see below).

In this embodiment, operation of association module 118C and inparticular the use of a threshold value by association module 118C isdepicted. As explained thoroughly below in FIGS. 3 and 4, associationmodule 118C may use the threshold value in order to associate a receivedword with a domain table. Association module 118C may associate a domaintable with a received word if the frequency of occurrence of the wordsatisfies a threshold value within the domain table (see below).

In this embodiment, threshold value 202 is set at 0.00000160%.Association module 118C may use threshold value 202 to associate thetemporal frequency of use of mafficking domain table with the wordmafficking. Association module 118C determines whether, within thisdomain table, the word mafficking has been used at a higher value thanthe threshold value 202 for a particular temporal increment. In thisembodiment, the usage value for mafficking is higher than thresholdvalue 202 at a temporal increment corresponding to the period between1920-1940. Accordingly, association module 118C associates maffickingwith the time period of 1920-1940.

In this embodiment association module 118C, using threshold value 202associates mafficking to a particular section of the domain table (i.e.time period of 1920-1940 within the domain table); however, it should beappreciated that in other embodiments, association module 118C mayassociate a domain table with a received word in its entirety. Forexample, a word may be associated with a medical frequency domain table,and not just a particular section within the medical frequency domaintable.

FIG. 3 is a flowchart depicting operational steps of a method for aDomain-based Semantic Analysis Program 108A and 108B, in accordance withan embodiment of the present invention. In this embodiment, the wordnecklace from a sentence “patient has an orange necklace” is analyzed.In reference to FIGS. 1, 2, and 3, steps of method 300 may beimplemented using one or more modules of a computer program, forexample, Domain-based Semantic Analysis Program 108A, and executed by aprocessor of a computer, such as computer 102. It should be appreciatedthat FIG. 3 does not imply any limitations with regard to theenvironments or embodiments which may be implemented. Many modificationsto the depicted environment or embodiment shown in FIG. 3 may be made.

At 302, the operation of receiving module 118A is depicted. Receivingmodule 118A may receive a digital text stream comprising one or morewords, and/or corresponding metadata, from an electronic input source.Receiving module 118A may receive the word(s) from a user or a computerimplemented system. Non-limiting examples of an input source may bespoken words, typed words, or inputting a corpus electronically from acomputer implemented source such as an electronic device (e.g. cellphones or tablets).

In this embodiment, receiving module 118A, receives a sentence (“patienthas an orange necklace”) from a computer implemented system. Forexample, receiving module 118A receives the words electronically from anannotation software used by a doctor. Receiving module 118A may receiveadditional metadata indicating that the domain of the words in thereceived sentence is medical.

At 304 the operation of determination module 118B is depicted.Determination module 118B may determine a value corresponding to afrequency of occurrence of a received word within a set of one or moredomain tables. A domain table comprises one or more arrays of aggregatedstatistical information about words, within a particular domain, and oneor more of corresponding word-senses and/or temporal properties, asdescribed in connection with FIG. 2.

Domain Table(s), in an embodiment, may be pre-loaded into Domain-basedSemantic Analysis Program 108A, or retrieved from communication network110 by Domain-based Semantic Analysis Program 108B. In otherembodiments, the domain table(s) could be generated by the user oranother computer implemented system. In various embodiments,Domain-based Semantic Analysis Program 108A or 108B may receive domaintable(s) or determine a selection of domain table(s) from a user or acomputer implemented system. For example, when a user is interested insemantic analysis of a word within a specific time period or semanticanalysis of a word within the context of a certain domain, determinationmodule 118B may receive a set of domain table(s) from the user orreceive instructions from the user as to which domain table(s) to use.For example, when receiving a word from a computer system, correspondingmetadata associated with the received word may be used to determine theselection of domain table(s).

Determination module 118B may also determine a selection of domaintable(s) based on previous analysis; Domain-based Semantic AnalysisProgram 108A or 108B may assign a context value to one or more wordswithin a corpus based on the semantic analysis which Domain-basedSemantic Analysis Program 108A or 108B has performed. Determinationmodule 118B may use that context value in order to determine a selectionof domain tables when analyzing other words within that corpus. Contextvalue is an indicator which may associate the analyzed word with acontext. A non-limiting example of a context value is metadata which maybe attached to a word in order to indicate the nature and context ofthat word. For example, Domain-based Semantic Analysis Program 108A or108B may analyze a word, within a corpus, and assign an 18^(th) centurycontext value to said word (i.e. the determination module 118Bdetermines that the word is from the 18^(th) century); when analyzinganother word within the same corpus, determination module 118B maydetermine a selection of domain tables which correspond to 18^(th)century based on the 18^(th) century context value.

Determination module 118B may also determine the frequency of occurrenceof the received word within domain table(s). It should be noted thatdetermining the frequency of occurrence is not the same or exclusive tofrequency of occurrence domain tables. Determination module 118B maydetermine the frequency of occurrence of the received word within adomain table which may be, for example, a frequency of co-occurrencedomain table.

In this embodiment, using the metadata received by the receiving module118A, determination module 118B determines a selection of domaintables(s) based on the medical nature of the word “necklace”.Determination module 118B may choose medical frequency domain table,veterinary frequency domain table, temporal frequency domain table, (forexample early 20^(th) century), medical co-occurrence domain table,veterinary co-occurrence domain table, a word-sense domain table (e.g. adictionary), and a legal domain table based on the metadata received byreceiving module 118A. It should be appreciated that a legal domaintable, in this embodiment, may be selected due to a possible legalmeaning of some words used in the medical field. Furthermore, in thisembodiment, determination module 118B, determines the frequency ofoccurrence of the word necklace within the above-mentioned domaintables.

At 306, the operation of association module 118C is depicted.Association module 118C may associate one or more domain table(s) withthe received word. This association may be based on a value thatcorresponds to frequency of occurrence of the received word within adomain table meeting a threshold value. For example, if the frequency ofoccurrence value in a domain table satisfies a threshold value (e.g. theword has been used more times than a threshold value), associationmodule 118C may associate that domain table to the received word.

The threshold value may be predetermined or input by a user. Forexample, if the user desires a higher threshold value due to the natureof the received word, Domain-based Semantic Analysis Program 108A or108B may receive an instruction or set of instructions to use a higherthreshold. In another example, Domain-based Semantic Analysis Program108A or 108B may determine a threshold value based on the metadataassociated with the received word. For example if the metadata indicatesthat the word is inherently ambiguous (i.e. pertains to more than oneinterpretation; having a double meaning) a higher threshold value may beused. A high threshold value corresponds to a high frequency ofoccurrence within a domain table.

In this embodiment, association module 118C determines a high thresholdvalue based on the metadata which points to the possible medical natureof the word necklace. Association module 118C determines a highthreshold, which corresponds to a high degree of certainty (alsoreferred to as a confidence value), because the word is of medicalnature and accuracy of word-sense identification may be more importantfor a medical word than, for example, a word which is predominately usedfor colloquial purposes.

In this embodiment, association module 118C may associate the wordnecklace from the sentence “patient has orange necklace” to the medicalfrequency domain table, veterinary domain table, medical co-occurrencedomain table, and veterinary co-occurrence domain table because the wordnecklace has a high frequency of occurrence within said domain tables;this may be due to high occurrence of the word necklace within theabove-mentioned domain tables. For example, the word necklace has a highfrequency of occurrence within the medical/veterinary frequency tableand a high frequency of co-occurrence with the word patient within themedical/veterinary co-occurrence domain tables (e.g. the word necklaceand “patient” co-occur within the same sentence very frequently).Furthermore, in this embodiment, association module 118C does notassociate necklace with a domain table which corresponds to early20^(th) century because the frequency of usage of necklace, asdetermined by the determination module 118B, is not higher than athreshold value with respect to that domain table.

At 308, operation of analyzing module 118D is depicted. Analyzing module118D may determine a word-sense of the received word based oncorresponding word-senses in the associated domain table(s) or acorresponding domain dictionary, or both. Analyzing module 118D may alsocommunicate the one or more word-senses and corresponding confidencevalues to the user or another computer-implemented system. In anembodiment, analyzing module 118D may search within the associateddomain table(s) and semantically analyze the received word based on thecorresponding word-sense of the received word in associated domaintable(s). In various embodiments, analyzing module 108D may use a domaindictionary which corresponds to the associated domain table determinedby the association module 118C. For example if a word satisfies athreshold value and is associated with a “medical co-occurrence domaintable”, analyzing module may use semantic analysis based on thecorresponding word-sense of the received word within the “medicalco-occurrence domain table” or a word-sense dictionary which correspondsto the medical terms, or both.

In another embodiment, analyzing module 118D may assign a confidencevalue to one or more word-sense. The confidence value may be based onthe degree of frequency of the word within the associated domain(s), andmetadata received by the receiving module 118A. Confidence value mayrepresent the degree of certainty that the word-sense presented by theDomain-based Semantic analysis program 108A and 108B. The higher theconfidence value, the higher the possibility of the word-sense beingaccurate.

Word-senses may be associated with a higher confidence value, if thefrequency of occurrence of the word(s) is higher within the associateddomain table(s), therefore a higher confidence value may also correspondto a higher threshold value (as explained above). Analyzing module 118Dmay also assign a word to a confidence value, rank the results based onassigned confidence values, and present multiple word-senses and theircorresponding confidence values to the user. For example, the word“admissible” in the sentence “this document is admissible” may beassociated with both a legal domain table and a word-sense domain table(e.g. a dictionary) because “admissible” has a high frequency ofoccurrence in both domain tables and satisfies a threshold. However thecorresponding word-senses from these two domain are different. Legaldomain table may have a corresponding word-sense such as “tangibleevidence that may be introduced to a factfinder” whereas a regulardictionary domain table may have a corresponding word-sense such as“having the right to be admitted to a place”. Since determination module118B may determine that the frequency of occurrence of the word“admissible” within the legal domain table is higher than a word-sensedictionary, analyzing module 118D may assign a higher confidence valueto the word-sense from the legal domain table and a lower confidencevalue to the word-sense from the word-sense domain table.

In this embodiment, analyzing module 118D determines a word-sense of theword necklace within the associated domain tables (associated by theassociation module 118C). Analyzing module 118D, for example, determinesthat:

-   -   according to the medical co-occurrence domain table, “necklace”        has a word-sense of “skin rash encircling the lower neck”, when        the word necklace has co-occurred with the word “patient” within        the same sentence;    -   according to the medical frequency of occurrence domain table,        necklace has a word-sense of “skin rash on the lower neck”;    -   according to the veterinary frequency of occurrence table,        necklace has a word-sense of “a band of color across the lower        neck”;    -   according to the veterinary frequency of co-occurrence table,        necklace has a word-sense of “colors of lower neck” when the        word necklace and “patient” have co-occurred;    -   according to the word-sense domain table, necklace has a meaning        of “jewelry”.        In this embodiment, analyzing module 118D ranks the domain        tables based on confidence value. Based on frequency of        occurrence within the associated domain table and metadata        received by receiving module 118A, analyzing module 118D assigns        a confidence value of 90% to “skin rash encircling the lower        neck”, 50% to “jewelry” word-sense, and 65% to a “band of color        across the lower neck”. Analyzing module 118D ranks these domain        tables according to their corresponding confidence values and        communicates them to the user.
